I am unable to use voice command to play my Google Play Music playlists. This is a feature supported on Google Home and comes in handy if you don't want to pay for a premium music service to play the music you want to hear. Does this Insignia speaker support this function?

Thanks for addressing this. I contacted Google this morning and playlists require a premium subscription, so the speaker probably does support them. I was just given bad information by the original google specialist who told me that it was a free functionality.
